To all whom it may concern: 2

Be it known that I, Cnns'rnn R. Sn'rron, a citizen of the United States, residing at Tucson, in the county of Pima, State of Alizona, have invented certain new and useful Improvements in Cooling Systems, of which i the following is a specification.

y invention relates to various features of novelty and improvement in cooling systems, and more particular-l but not restrictedly, pertains to advantageous structural features in what may be termed an The action of this fan may or augmented so far as the iceless refrigerator system, employing the Well-known principle of the rapld evaporation or vapori atlon of a liquid, such as Water, to produce the cooling efiect. The improved system is equally available for use in maintaining rooms or houses at a reduced tern erature.

'l e prime object or leading feature of the present invention is the production of an appliance or system of this character which is simple in structure, economical to produce, results. p

The invention resides in the mechanical construction of the various parts and their association and cooperation with one another, producing by their combined action the required function in a better, simpler, and more complete and efiective manner than has heretofore been possible.

In the preferred embodiment of the invention, means are employed for humiditying or moistening the air which is delivered to the room, house, or compartment containing the iceless refrigerator, and means are also used for causing an adequate circulation of the air to accomplish the evaporation of the moisture suficiently rapidly to produce the desired cooling efi'eet.

In the particular embodiment of the invention presented in this application, a water-driven air-fan, either wholly or in part, creates the desired air flow and the water used for driving or rotating the fan is also employed for moistening or humidifying the air and reducing its temperature. be supplemented production of a draft or air current is concerned, and the neo vaporization assisted, b means of and efi'ective in the obtaining of I a heating appliance which pe 'ormsthis double useful function of facilitating and aiding the travel of the air and augmentmg Specification of Letters Patent.

or hastening the required evaporation of the moisture.

In order that a full and complete understanding of the invention and its various benefits and advantages may be had, I have illustrated a preferred and desirable embodiment of the same in the accompanyin drawin s throughout the views of whic like re erence characters refer to the same parts. 1

Referring to the drawing:

igure 1 illustrates in section, andmore or less diagrammatically, the complete system or apparatus, and

Fig. 2 is an enlarged section on lines 2-2 of Fig. 1 Water-power.

The appliance includes a compartment, 7, (such as a room, house, or other chamber), which may or may not house or containan icelessrefrigerator 8, conveniently formed of. a suitable framework covered with a tentile fabric 9, such as cotton-cloth, therefrigerator being supplied, as is customary, with a plurality of reticulated or openwork shelves or ledges 10, adapted to support the articles to bemaintained in cool condition.

This compartment 7, by means of a conduit 11, is connected to a chamber 12 provided with a central air inlet or admission tube or pipe 13 extending downwardly thereinto a substantial distance, as shown, and supported on brackets 14, 14:. Such pipe or tube 18 and the chamber 12 contain a retatably-mounted vertical shaft 15 carrying a horizontal duplex air-fan structure compris ,ing inner blades orvanes 16 in the tubel? and outer reversely-pitched or oppositely-in clined blades or vanes 1'? located in the space between the tube 13 and the wall of the chamber. The outer portion of this fan is composed of a ring 18 carrying a series of buckets or finsil9 against whlch a jet of water delivered from a nozzle 20 plays so as to bring about a rapid rotation of the fan. Such fan also comprises an inner ring- 21 between the blades 16 and 17 ierming a directintermediate continuation of the tube.

13 as shown in Fig. 1, being of, practically the same diameter as thatof the tube. The lowenportion of the chamber 12 is provided with a drain 22, and, in addition, the two compartments 7 and 12 at their lower por- "tions are eonnected'by an inclined pipe 23, whereby any water tending tocollect in the Patented Apr, 2%, 19159) I for the air.

' ing lower portion of the compartment 7 wiH automatically flow intothe chamber 12 and from such chamber be drawn ofi through the drain 22.

The upper portion of the compartment 7 by a tube or pipe 24 is connected to a heater 25 which in turn has a discharge pipe 26 Heater 25 is internally supplied with two headers 27 and 28 connected together by a plurality of tubes 29, somewhat like an ordinary tubular boiler, so that the air in the pipe 24.- can readily pass through such tubes 29 to the discharge pipe 26. The heater comprises a gas or other burner 30, the heated products of combustion from which through tube 31 to the space between the headers and from such compartment 32 they flow ofi at the top through the dehvery ipe 33, the chamber 32, however, preferably being equipped with a pair of bafiie lates 34 and 35 necessarily causing an in irect or tortuous flow of the heated air from the burner through such chamber before it is delivered into the discharge pipe 33. It will be readily understood, however, that the products of combustion from' the burner 30 do not in any way come in contact with the air passing through the heater 25. Obviously, an other suitable style or type of heater might be used with much the same advantage.

The operation of the apparatus occurs practically as follows;

The duplex fan or blower 16, 17, is rapidly rotated by means of the jet of water from the nozzle 20 directed against the vanes or fins 19. This causes rapidly let pipe 13 and then such air, in passmg upwardly between the tube 13 and the casing wall 12, is acted upon by the reverse fan 17, the two fans thus working in conjunction to deliver the air through the tube 11 into the compartment 7. It will be observed, however, that the water employed in drivthe fan is also used to moisten or humidify the air and also to cool it, such water in striking the vanes being sub-divided or spattered or spra ed so that the air passing t rough the app iance becomes adequately charged with cool moisture and at the same time cooled. The surplus water, of course, drains ofi' through the pipe 22 and any excess water in the compartment 7 likewise drains ofi' through the pipes 23 and 22.

If desired, the water may be permitted to accumulate in chamber 12 sufficiently so that tube 13 projects into it slightly, whereby fan 16 positively forces the blast of air through the water which of course during this action would become charged with moisture.

This cool, moisture-laden air causes the required coolin effect in compartment 7 and on the refrigerator contents. In order the fan 16 to spin and to draw in air through the in-' to augment or increase the flow of air, the passage or draft of the air is supplemente by the action of the heating appliance. That is to say, the heating of the air in the device 25 creates a draft or suction in the tube 24: and compartment 7, thus increasing the air current flow and augmenting its cooling function.

While I have herein presented only one desirable embodiment of the invention, it is to be understood that it is susceptible of a variety of embodiments, and that many minor mechanical changes may be made in the apparatus as presented wlthout departure from the substance and essence of the invention and without the sacrifice of any of its substantial benefits and advantages. For example, if desired, the heating appliance may be omitted, but for the most effective work under ordinary conditions it is found to be advantageous. Tnstead of using a duplex or compounolfan 16, 17, a fan or blower of difi'erent or simpler construction might be used, and instead of driving it by water power, it could be rotated by other means an the moisture supplied in any con venient Way. Stated somewhat otherwise, to those skilled in this art various suggestions for minor changes will present themselves, all of which are embraced within the scope of the invention as defined by the appended claims.

The appliance as will be appreciated, comprises both an air washing and cooling system which may be used to advantage either with or without the iceless refrigerator because, even with such refrigerator absent, the compartment 7 is cooled by the passage of the cool humidified air therethrough.
